LITTLE ROCK (AP) — A hearing has been set in a lawsuit brought by a group of same-sex couples challenging Arkansas’ ban on gay marriage.

Online court records show that a hearing is scheduled for Dec. 12 in state court.

A group of same-sex couples filed the lawsuit against a number of county clerks and the head of the Arkansas Department of Finance and Administration this year.

The couples are seeking a preliminary injunction and declaratory judgment barring the enforcement of a constitutional amendment that Arkansas voters approved in 2004. That amendment defines marriage as between a man and a woman.
